The short answer: in Australia, the first thing to check is not the plan but whether your phone meets the local network requirements. All Australian 3G networks closed in 2024. As a result, handsets without VoLTE are blocked from the networks outright, and handsets without Band 28 (700 MHz) lose coverage the moment you leave a major city. A phone that works perfectly at home is not automatically fine here. Clear those two requirements and the rest is easy, because an eSIM can be installed before you leave home and needs nothing on arrival.
This guide walks through the device requirements first, then the setup steps from departure to arrival. Plans are on the Australia eSIM page.
Why an eSIM for Australia depends on your device, not your plan
Australia is an unusual destination in network terms. The country is vast and the population sits along the coast, so carriers have concentrated their networks on low frequencies that travel a long way. Australia also completed its 3G shutdown more thoroughly than most countries, and devices that fall short of the new requirements either cannot connect or are removed from the network by regulation.
Before comparing any plans, confirm three things about your handset:
- It supports eSIM.
- It supports VoLTE, meaning voice calls over the 4G network.
- It supports Band 28 (700 MHz).
The first applies to every destination. The second and third are effectively Australia-specific, and they are where travellers get caught out.
What the Australian 3G shutdown changed for visiting phones
Handsets without VoLTE are blocked from the network
Australian 3G networks began shutting down on 28 October 2024 and were switched off nationwide within the following week. The consequence is regulatory as well as technical. The Australian Communications and Media Authority requires carriers to identify handsets that cannot reach the emergency number Triple Zero (000), notify the customer, and then block the device from the network.
This does not only cover 3G-only handsets. It also covers 4G handsets that rely on 3G for voice and emergency calls through circuit switched fallback, in other words any device without VoLTE. Even if you only intend to use data, the restriction applies to network access itself.
Visiting handsets are not exempt. Japanese carrier SoftBank published a notice in December 2024 confirming that international roaming in Australia had stopped working for a number of its handset models, citing exactly these two causes: no VoLTE roaming support, and no Band 28 support.
Without Band 28 you lose signal as soon as you leave the city
Alongside the 3G shutdown, Australian carriers moved to LTE networks built around Band 28 (700 MHz). Telstra states plainly that Band 28 is its main 4G frequency and that phones bought overseas or second-hand may not connect to its 4G network because that frequency is not standard in many other countries.
A low frequency such as 700 MHz travels far from each tower, which is what makes it suitable for a sparsely populated country. The flip side is that a phone without Band 28 may work on other frequencies in central Sydney or Melbourne and then drop to no service on the Great Ocean Road, in Tasmania, or anywhere near Uluru. The further your itinerary goes from the cities, the more this matters.
Check the manufacturer's specification sheet for your exact model rather than assuming. Tablets are a common blind spot: several iPad models were named in carrier notices as unable to roam in Australia.
The pre-departure eSIM and device checklist
Work through these four checks before you fly. All of them can be done at home.
- eSIM support. Confirm you can add an eSIM in your settings. If you are unsure, see how to check eSIM compatibility.
- Carrier lock. A locked handset will not accept another provider's eSIM. See unlocked phones and eSIM.
- VoLTE. Check that VoLTE or 4G calling is switched on. If the setting does not exist at all, your handset may not support it.
- Band 28. Look for "LTE Band 28" or "700 MHz" in the supported frequency list on the manufacturer's spec page.
If any one of the four is missing, you will hit dead spots in Australia. In that case decide on the hardware before you buy a plan: either travel with a compatible handset or fall back to a rental device. eSIM versus pocket WiFi covers that trade-off.
How to set up your Australia eSIM
Once the device checks pass, the process is straightforward.
- Choose an Australia eSIM that matches your dates.
- Install it at home over your own Wi-Fi, by scanning the QR code or adding it in the app.
- Set your default data line to the travel eSIM so it takes over on arrival.
- On landing, turn off airplane mode and switch data roaming on.
Installing is not the same as activating. Most travel eSIMs start counting from the moment they register on a local network, so install at home on a stable connection. Doing it on airport Wi-Fi risks the download being interrupted and the profile needing to be reissued. The full walkthrough is in how to set up an eSIM for travel.
If nothing connects after you land, check data roaming, then the default line, then the APN, in that order. Keep eSIM not working on arrival and APN settings to hand.
Local prepaid SIM or travel eSIM for Australia
Buying a local prepaid SIM in Australia means an identity check. Under ACMA rules a carrier cannot activate a prepaid service without verifying your name, date of birth and address. For a visitor that means queueing at a counter on arrival and giving an address you may only have booked for three nights.
For a short trip, skipping that process is the practical advantage of an eSIM. If you are on a working holiday or staying long term and need a local number, a local contract makes more sense. See connectivity for a working holiday.
Using your home carrier's roaming is a third option, but as noted above, handsets without VoLTE roaming simply will not connect. International roaming versus eSIM compares the two.
Coverage in Australia differs sharply between cities and regions
In Sydney, Melbourne, Brisbane and Perth you will rarely have a problem on any of the three networks. The gap opens up once you leave them.
- Scenic routes such as the Great Ocean Road and the Blue Mountains have stretches with no usable signal.
- Uluru and the outback have very few towers to begin with.
- Tasmania involves long drives, and mountain sections can stay out of range for a while.
On those stretches, Band 28 support is the difference between having service and not. If your itinerary leaves the cities, also confirm that tethering is available on your plan and download offline maps before you go.
How much data an Australia trip actually needs
Data use depends on behaviour rather than trip length. As a rough guide:
- Maps, search and messaging: roughly 0.3 to 0.5 GB a day, so around 3 GB for a week.
- Sharing photos and short videos as you go: around 1 GB a day, so 7 to 10 GB for a week.
- Streaming or daily video calls: 2 GB a day or more, where an unlimited-style plan is simpler.
Australia involves long drives, and navigation tends to run for hours at a time. Expect to use more than you would on a trip of the same length in Asia or Europe.
FAQ
Will any iPhone work with an eSIM in Australia?
eSIM itself works on iPhone XS and later, but Australia also requires VoLTE and Band 28. Most recent iPhones support both. Tablets are the exception to watch: several iPad models have been listed by carriers as unable to roam in Australia.
When should I buy and install my Australia eSIM?
Buy and install a few days before departure, over your home Wi-Fi. Activation usually begins when the profile registers on an Australian network. Starting the process at the airport risks an interrupted install on congested public Wi-Fi.
How do I check whether my phone supports Band 28?
Open the manufacturer's specification page for your exact model and look through the supported LTE frequencies for "Band 28" or "700 MHz". If it is not listed, assume it is not supported and plan another option for any travel outside the cities.
Does an Australia eSIM give me a phone number?
Data-only eSIMs do not include a number. App-based calling covers most situations. eSIM and phone numbers explains how to keep your existing number reachable.
Is buying a SIM at the airport faster?
Sydney and Melbourne airports both have sales counters, but you still need the identity check and activation wait, and arrival peaks produce queues. Airport SIM versus eSIM compares them.
Check the device requirements first and the rest of your Australia eSIM decision is easy
Australia is a destination where the handset matters more than the plan. Confirm VoLTE and Band 28 before you fly and any reasonable plan will serve you well in the cities. Skip that check and even the largest data allowance will not help you outside them.
Once your device is confirmed, pick an Australia eSIM that matches your dates and install it before you leave.
